Materials –
lkeep lids on containers of solvents;
lonly use the minimum quantity;
lconsider alternative materials;
lminimise over-spray when painting.
Gases –
luse the correct equipment for collecting
refrigerants;
ldon't burn rubbish on site.
Discharges to water
Most sites will have two systems for discharging
water: storm drains and foul drains. Storm drains
should only receive clean water, foul drains will take
dirty water.
The foul drain will accept many of the normal waste
waters such as washing water, detergents and
domestic type wastes, but oil, petrol, solvent, acids,
hydraulic oil, antifreeze and other such substances
should never be poured down the drain. If in any
doubt, speak to the local Water Company first.
Every precaution must be taken to prevent spillage of
oil, fuel, solvents etc. reaching the drains. All
handling of such materials must take place well away
from the drains and preferably in an area with a kerb
or wall around it, to prevent discharge into the drain.
If a spillage occurs, it should be soaked up
immediately. Having a spill kit available will make this
easier.
Additional precautions
Check whether the surface water drains are
connected to an oil/water separator, this could
reduce the pollution if an incident was to occur. Oil/
water separators require regular maintenance to
ensure effectiveness.
Checklist
Always adhere to the following:
Disposal –
lnever pour anything down a drain without first
checking that it is environmentally safe to do so,
and that it does not contravene any local
regulations or bye-laws;
lhave oil traps emptied regularly.
Spillage prevention –
lstore liquids in a walled area;
lmake sure the taps on liquid containers are
secure and cannot be accidentally turned on;
lprotect bulk storage tanks from vandalism by
locking the valves;
ltransfer liquids from one container to another in
an area away from open drains;
lensure lids are replaced securely on containers;
lhave spill kits available near to points of storage
and handling of liquids.Spill kits
Special materials are available to absorb a number of
different substances. They can be in granular form,
ready to use and bought in convenient containers for
storage. Disposal of used spill-absorbing material is
dealt with in the 'Waste Management' section.
Land contamination
Oils, fuels and solvents etc. can contaminate any soil
that they are allowed to contact. Such materials
should never be disposed of by pouring onto soil and
every precaution must be taken to prevent spillage
reaching soil. Waste materials stored on open
ground could also leak, or have polluting substances
washed off them that would contaminate the land.
Always store these materials in suitable skips or
other similarly robust containers.
Checklist
Always adhere to the following:
ldon't pour or spill anything onto the soil or bare
ground;
ldon't store waste materials on bare ground, see
'Spillage prevention' list.
Legal compliance
Some sites may have a discharge consent for
effluent discharge to the foul drain for a car wash etc.
It is important to know what materials are allowed in
the drain and to check the results of any monitoring
carried out by the Water Company.
Where paint spraying operations are carried out it
may be necessary to apply to the Local Authority for
an air emissions licence to operate the plant. If such
a licence is in operation, additional precautions will
be necessary to comply with the requirements, and
the results of any air quality monitoring must be
checked regularly.
Checklist
Always adhere to the following:
lknow what legal consents and licences apply to
the operations;
lcheck that the emissions and discharges
comply with legal requirements.

Waste Management
One of the major ways that pollution can be reduced
is by the careful handling, storage and disposal of all
waste materials that occur on sites. Legislation
makes it illegal to dispose of waste materials other
than to licensed waste carriers and disposal sites.
This means that it is necessary to not only know what
the waste materials are, but also to have the
necessary documentation and licenses.
Handling and storage of waste
Ensure that waste materials are not poured down the
drain or onto soils. They should be stored in such a
way as to prevent the escape of material to land,
water or air.
They must also be segregated into different types of
waste e.g. oil, metals, batteries, used vehicle
components. This will prevent any reaction between
different materials and assist in disposal.
Disposal of waste
Disposal of waste materials must only be to waste
carriers who are licensed to carry those particular
waste materials and all the necessary
documentation must be completed. The waste
carrier is responsible for ensuring that the waste is
taken to the correct disposal sites.Dispose of waste in accordance with the following
guidelines:
lFuel, hydraulic fluid, anti-freeze and oil –
keep separate and dispose of to specialist
contractor.
lRefrigerant – collect using specialist
equipment and containers, and reuse.
lDetergents – safe to pour down the foul drain
if diluted.
lPaint, thinners – keep separate and dispose of
to specialist contractor.
lComponents – send back to supplier for
refurbishment, or disassemble and reuse any
suitable parts. Dispose of the remainder in
ordinary waste.
lSmall parts – reuse any suitable parts, dispose
of the remainder in ordinary waste.
lMetals – can be sold if kept separate from
general waste.
lTyres – keep separate and dispose of to
specialist contractor.
lPackaging – compact as much as possible and
dispose of in ordinary waste.
lAsbestos-containing – keep separate and
dispose of to specialist contractor.
lOily and fuel wastes (e.g. rags, used spill kit
material) – keep separate and dispose of to
specialist contractor.
lAir filters – keep separate and dispose of to
specialist contractor.
lRubber/plastics – dispose of in ordinary
waste.
lHoses – dispose of in ordinary waste.
lBatteries – keep separate and dispose of to
specialist contractor.
lAirbags (explosives) – keep separate and
dispose of to specialist contractor.
lElectrical components – send back to
supplier for refurbishment, or disassemble and
reuse any suitable parts. Dispose of the
remainder in ordinary waste.
lElectronic components – send back to
supplier for refurbishment, or disassemble and
reuse any suitable parts. Dispose of the
remainder in ordinary waste.
lCatalysts – can be sold if kept separate from
general waste.
lUsed spill-absorbing material – keep
separate and dispose of to specialist contractor.
lOffice waste – recycle paper and toner/ink
cartridges, dispose of the remainder in ordinary
waste.

General fitting instructions
Precautions against damage
To avoid damage to the vehicle when carrying out
repairs, always adhere to the following:
lAlways fit wing and seat covers before
commencing work. Avoid spilling brake fluid or
battery acid on paintwork; immediately wash off
with water if this occurs.
lDisconnect the battery earth lead before starting
work, see ELECTRICAL PRECAUTIONS.
lAlways use the recommended service tool or a
satisfactory equivalent where specified.
lProtect exposed bearing surfaces, sealing
surfaces and screw threads from damage.
Component removal
Whenever possible, clean components and
surrounding area before removal.
lBlank off openings exposed by component
removal.
lImmediately seal fuel, oil or hydraulic lines when
apertures are exposed; use plastic caps or
plugs to prevent loss of fluid and ingress of dirt.
lClose open ends of oilways exposed by
component removal with tapered hardwood
plugs or conspicuous plastic plugs.
lImmediately a component is removed, place it in
a suitable container; use a separate container
for each component and its associated parts.
lClean bench and provide marking materials,
labels, containers and locking wire before
dismantling a component.
Dismantling
Observe scrupulous cleanliness when dismantling
components, particularly when brake, fuel or
hydraulic system parts are being worked on. A
particle of dirt or a cloth fragment could cause a
serious malfunction if trapped in these systems.Use the following procedures:
lBlow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any
O-rings used for sealing are correctly replaced
or renewed if disturbed during the process.
lUse marking ink to identify mating parts and
ensure correct reassembly. Do not use a centre
punch or scriber to mark parts, they could
initiate cracks or distortion in marked
components.
lWire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
lWire labels on to all parts which are to be
renewed, and to parts requiring further
inspection before being passed for reassembly;
place these parts in separate containers from
those containing parts for rebuild.
lDo not discard a part due for renewal until after
comparing it with a new part to ensure that its
correct replacement has been obtained.
Cleaning components
Always use the recommended cleaning agent or
equivalent. Ensure that adequate ventilation is
provided when volatile degreasing agents are being
used. Do not use degreasing equipment for
components containing items which could be
damaged by the use of this process.
When washing under bonnet, never direct water onto
ECM, as water ingress may occur resulting in
damage to electrical components inside.
General Inspection
All components should be inspected for wear or
damage before being reassembled.
lNever inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an
incipient failure.
lWhen a component is to be checked
dimensionally against recommended values,
use the appropriate measuring equipment
(surface plates, micrometers, dial gauges etc.).
Ensure the measuring equipment is calibrated
and in good serviceable condition.
lReject a component if its dimensions are
outside the specified tolerances, or if it appears
to be damaged.
lA part may be refitted if its critical dimension is
exactly to its tolerance limit and it appears to be
in satisfactory condition.
lUse 'Plastigauge' 12 Type PG-1 for checking
bearing surface clearances.
GENERAL INFORMATION
03-10
Joints and joint faces
General
Fit joints dry unless specified otherwise.
lAlways use the correct gaskets as specified.
lWhen joining compound is used, apply in a thin
uniform film to metal surfaces; take care to
prevent joining compound from entering
oilways, pipes or blind tapped holes.
lIf gaskets and/or joining compound is
recommended for use; remove all traces of old
joining material prior to reassembly. Do not use
a tool which will damage the joint faces and
smooth out any scratches or burrs using an oil
stone. Do not allow dirt or joining material to
enter any tapped holes or enclosed parts.
lPrior to reassembly, blow through any pipes,
channels or crevices with compressed air.
Locking devices
General
Always replace locking devices with one of the same
design.
Tab Washers
Always release locking tabs and fit new locking
washers, do not re-use locking tabs. Ensure the new
tab washer is the same design as that replaced.
Locking Nuts
Always use a backing spanner when loosening or
tightening locking nuts, brake and fuel pipe unions.
Roll Pins
Always fit new roll pins of an interference fit in the
hole.
Circlips
Always fit new circlips of the correct size for the
groove.
Locking wire
Always fit locking wire of the correct type. Arrange
wire so that its tension tends to tighten the bolt heads
or nuts to which it is fitted.
Keys and Keyways
Remove burrs from edges of keyways with a fine file
and clean thoroughly before attempting to refit key.
Clean and inspect key closely; keys are suitable for
refitting only if indistinguishable from new, as any
indentation may indicate the onset of wear.
GENERAL INFORMATION
03-31
When a major repair has been completed, a leak test
should be conducted; refer to the air conditioning
section of this manual for the correct procedure.
Refrigerant oil
Use an approved refrigerant lubricating oil:
ND Oil 8
CAUTION: Do not use any other type of
refrigerant oil.
CAUTION: Refrigerant oil easily absorbs water
and must not be stored for long periods. Do not
pour unused oil back into the container.
When renewing system components, add the
quantities of refrigerant oil recommended in the Air
Conditioning section of this manual.
Compressor
A new compressor is sealed and pressurised with
Nitrogen gas. When fitting a new compressor, slowly
release the sealing cap; gas pressure should be
heard to vent as the seal is broken.
CAUTION: A new compressor should always be
sealed and could be pressurised with nitrogen
gas. To avoid possible oil loss, release the
sealing cap(s) slowly. Do not remove the cap(s)
until immediately prior to connecting the air
conditioning pipes to the compressor.
Rapid refrigerant discharge
If the air conditioning system is involved in accident
damage and the system is punctured, the refrigerant
will discharge rapidly. The rapid discharge of
refrigerant will also result in the loss of most of the
oil from the system. The compressor must be
removed and all the remaining oil in the compressor
drained and refilled in accordance with the 'Air
Conditioning Compressor Replacement Procedure'.
Air conditioning compressor
replacement
A new compressor is supplied filled with a full charge
of (X cm3) of refrigerant oil.
A new compressor is supplied with an oil fill (X cm) of
120 cm
3.
A calculated quantity of oil must be drained from the
new compressor before fitting. To calculate the
quantity of oil to be drained:
1Remove the drain plug from the old
compressor.
2Invert the compressor and gravity drain the oil
into a calibrated measuring cylinder. Rotate the
compressor clutch to ensure the compressor is
completely drained.
3Note the quantity of oil drained (Y cm
3).
4Calculate the quantity of oil to be drained from
the new compressor using the following
formula:
X cm
3 – (Y cm3 + 20 cm3) = Q cm3
5Remove the drain plug from the new
compressor and drain Q cm3 of oil.
6Fit and tighten the compressor drain plug.
System components
When renewing system components, add the
following quantities of refrigerant oil:
lCondenser = 40 cm
